Embodiment 1

[0025] ① Preparation of tussah silkworm chrysalis powder: Take 12 kg of tussah silkworm chrysalis, use Streptococcus tussah silkworm as the induction source, and adjust the bacterial concentration to 10 with sterile physiological saline. 7 1 / mL, injected into pupal body, inject 0.25 μL per silkworm pupae, culture at 22°C for 4-6 days, then break pupae body, centrifuge (room temperature, 5000rpm, 15min) to remove pupae shell and pupae body material, and then After spray drying, 2 kg of pupa powder can be obtained.

[0026] ② Mixing of raw materials: 2 kg of immune tussah silkworm chrysalis powder, 2 kg of white fish meal, 4 kg of shrimp bran powder, 4 kg of defatted soybean powder, 4 kg of corn flour, sargassum powder and sargassum powder prepared in the above step ① according to the quality 24 kg of mixed algae powder with a ratio of 3:1, sea mud powder and oyster powder are fully mixed with 39.2 kg of mixed powder and 0.8 kg of premix in a ratio of 1:1 by mass. The mixing pro...

Embodiment 2

[0029] ① Mixing of raw materials: 4 kg of white fish meal, 4 kg of shrimp bran powder, 4 kg of defatted soybean meal, 4 kg of corn meal, 24 kg of mixed algae powder with a mass ratio of 3:1 , sea mud powder and oyster powder are fully mixed with 39.2 kg of mixed powder and 0.8 kg of premix according to the mass ratio of 1:1. The mixing process is carried out in batches in the KCH-10V mixer.

[0030] ②Granulation of raw materials: The mixture in the above step ① is made into granules with a granulator.

Embodiment 3

[0032]Choose 10 kilograms of feed prepared in Example 1 to directly feed sea cucumbers, and the feeding time is 60 days. The volume of the culture tank is 1 cubic water body, the stocking density is 1 jin / cubic water body, and the pond is poured once every 7 days. The weight ratio of sea cucumber is 7:100.

Abstract

The invention relates to a stichopus japonicus feed and a preparation method and application thereof. The stichopus japonicus feed comprises tussah pupa powder prepared from tussah pupa subjected to immunosuppression induction. The stichopus japonicus feed is prepared from the following ingredients in parts by weight: 1-5 parts of immunized tussah pupa powder, 1-5 parts of white fish powder, 2-8 parts of shrimp chaff powder, 2-8 parts of defatted soybean powder, 2-8 parts of corn flour, 20-40 parts of sargassum and sargassum thunbergii mixed powder, 40-60 parts of sea mud and oyster mixed powder and 0.5-1 part of a premix. The preparation method of the stichopus japonicus feed comprises the steps of preparing the raw materials, mixing and granulating. The stichopus japonicus feed has the advantages that the raised stichopus japonicus has high immunity, high growth rate and good quality, the economic benefits of farmers and farming enterprises of the stichopus japonicus can be greatly improved, the using amount of antibiotics in holothurian culture is effectively lowered, and the tussah resource application field is expanded.

Description

technical field [0001] The invention relates to a sea cucumber feed, in particular to a sea cucumber feed and its preparation method and application. Background technique [0002] At present, sea japonicus seed cultivation in northern my country is mostly indoor artificial cultivation, and the cultivation cycle is half a year to one year, mostly one year. During the breeding process, fishmeal is the main source of animal protein in their feed. However, as the price of international fishmeal market continues to rise, cost pressures continue to increase. Some low-quality fishmeal on the market are widely used because of their low prices. Long-term feeding of these Inferior fish meal not only easily leads to the lack of nutrition of seedlings, resulting in growth retardation and low disease resistance, but also often carries pathogenic bacteria and chemical preservatives in fish meal, which can easily cause disease and death of seedlings. In actual production, farmers often us...
